In v2024.10, "make envtools" is broken for at least these defconfigs:
am335x_evm_defconfig rpi_3_defconfig rpi_4_defconfig mx7dsabresd_defconfig wandboard_defconfig imx8mp_evk_defconfig
The only defconfig we use for which it is not broken is stm32mp13_defconfig. They all work just fine in v2024.07.
The symptoms are slightly different, but all related to the fact that some transitively included header uses IS_ENABLED or CONFIG_IS_ENABLED without linux/kconfig.h having already been included.
A simple git bisect doesn't produce anything sensible, it ends up at 3a9f642ca94 (crypto: nuvoton: npcm_sha: Support SHA 384/512) which clearly has nothing to do with this. But digging deeper, one eventually finds 0f92fa45603 ("env: Remove <common.h> and add needed includes").
So at first I tried adding "#include <linux/kconfig.h>" in include/env_default.h and include/env_flags.h. That fixes it for some, but not all, of the above. For example rpi_3_defconfig still fails, then in log.h complaining about BIT() and u8 not being defined. At least BIT() is should have gotten from bitops.h, except that that's behind ifdef __KERNEL__, so not set for the envtools build.
It turns out that the envtools source code in fw_env_private.h already has some hackery to deal with all this, in the form of the __ASSEMBLY__ games it plays before including config.h. It seems that if we just make sure to do that include early enough, so that config.h is indeed parsed with that __ASSEMBLY__ hackery in place, everything builds fine.
